Speeificationof Letters Batent. 'Patgnted Ap 25 1922,

Application filed June 25, 1921. Serial No. 480,322.

To all whom/it may concern. I

Be it known that I, Jnssn T Fins-E, a citizen of the United States, residlng at Fresno,

- county of Fresno, Stateof California, have invented certain new and useful Improvements in Adjustable Bails; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings,

and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in printing presses, and partlcularly to a paper feed mechanism thereof, such as is shownv generally in the type of printing .press in United States Patent No. 1,016,756, dated Feb. 6th, 1912, and United States Patent No. 1,041,314, dated Oct. 15th, 1912.

The principal object of my invention is to provide for adjustment of the bail feedroll so that the paper will be gripped and fed over the lower feed plate and into the plane of the printing cylinder with equal pressure on both ends, and without disturbing either the driving arrangement of the roll, or the fixed spacing of the same relative to the bail-post roller.

A further object'of the invention is to producea simple and inexpensive device and yet one which will be exceedingly effective for the purposes which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Fig. 1 is a top plan view of the complete paper-feed mechanism, the adjustable bail structure being emphasized.

Fig. 2 is an end view of the same, the nearest dolly-box being removed. 7

Fig. 3 is a detachedrear view of the assembled bail and feed-roll structure.

Fig. 4 is a perspective view of the bail itself.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes the side frames of the press, on which are fixed the dolly-boxes 2,

between and in which is journaled the prii1ting cylinder 3, carrying a driving. gear 4 on one end, meshing with a rack 5 on the mov-. ingrbed of the press. z

o the rear of the cylinder 3, and on the side. thereof opposite the gear 4, is the-bail post 6, pivotally mounted to the adjacent dolly box 2 by means of a pinor'bearing member 7', and carrying on its opposite end the bail-post feeler-roller 8.

Positioned between the post 6 and the opposite box 2 is the bail 9, comprising a rigid horizontal bar 10 having a narrow vertical arm 11 'on one end provided with a bearing orifice 1 2 to receive the pivotal post-pin 7 and having on the other end an pin 16 Ytherethrough,v which also pass es through the adjacent box 2.

On the bearing 16 is mounted anqidler pinion 17 interposed between the gear 4 and a pinion 18 on the adjacent end of the bail feed-roll 19, which is ournaled at that end in the orifice 15 of the bail arm, and at the other endv in a collar ,20 itself turnably mounted in the post '6. p

Projecting through the bar 10 and threaded into the collar 20 is an adjustment screw bearings 7 and 16- as axes, and as the ball ion it will i feed-roll 19 is fixed at one end in the said post, and at the other end in the bail, itis evident that with the swivel movement of said bail about its axes, the horizontal alinement of the feed roll will be altered. Such I movement is controlled and governed by the screw 21, so that the said roll may be set exactly parallel to the. lower feed roll' '23,'which is securely fixed to the boxes 2.'

the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention; as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is 1. An adjustable bail structure comprising a bail post, a bail pivoted to the post, a feed roll journaled in the post and in the opposite end of the bail, and means between the bail and roll at the end thereof adjacent the bail post for altering the horizontal level of the feed roll at the other end.

2. An adjustable bail structure comprising a bail post, a bail pivoted to the post, a feed roll j ournaled in the post and in the opposite end'of the bail, a block turnably mounted in the bail post and in which the adjacent 3 end of the feed roll is journaled, and a headed adjustment screw passing through the bail and threaded into the block. 7

8. An adjustable bail structure for print ing presses comprising a bail post journaled 35 in a fixed member of the press, a bailextending transverse of the press and journaled on the press in common with the post at one end and on the press alone at the other end, a feed-roll member journaled in the post and in the opposite end of the bail, and means 't'or moving the bail about its pivotal connections with the press, whereby the hori- I zontal-level of the feed-roll will be altered.

In testimony whereof I afiix my signature. 45
